You are absolutely wrong! The writers of the Bible were inspired by God and wrote exactly what He told them to write. I will agree with one thing you are saying though. Some interpretations have been wrongly translated. You have to go back to the original texts and most of the translators are too lazy to do that so they put what they think was originally written.

I believe Jonathan Merritt is replacing the word “do” with the word “endure” which is his interpretation and according to Revelation 22:18-19, it says “I warn everyone who hears the words of the prophecy of this book: if anyone adds to them, God will add to him the plagues described in this book, and if anyone takes away from the words of the book of this prophecy, God will take away his share in the tree of life and in the holy city, which are described in this book.”

The Greek translation issue of the word in question "do" has already been dealt with up the thread. Why do you Christ-ees always start threatening hellfire on anyone who disagrees with you because they actually spent time studying the text and context of the verse? Who says YOUR interpretation is the right one? Perhaps a little less condemnation and a little more Christlikeness on your part?
